help understanding log files and TLS

[Greg Matthews <gmatt@nerc.ac.uk>]

Can someone tell me what the line:
TLS trace: SSL3 alert write:fatal:protocol version
means in the following log snippet:

connection_get(22): got connid=18
connection_read(22): checking for input on id=18
TLS trace: SSL_accept:before/accept initialization
TLS trace: SSL_accept:SSLv3 read client hello A
TLS trace: SSL_accept:SSLv3 write server hello A
TLS trace: SSL_accept:SSLv3 write certificate A
TLS trace: SSL_accept:SSLv3 write server done A
TLS trace: SSL_accept:SSLv3 flush data
TLS trace: SSL_accept:error in SSLv3 read client certificate A
TLS trace: SSL_accept:error in SSLv3 read client certificate A
connection_get(22): got connid=18
connection_read(22): checking for input on id=18
TLS trace: SSL_accept:SSLv3 read client key exchange A
TLS trace: SSL_accept:SSLv3 read finished A
TLS trace: SSL_accept:SSLv3 write change cipher spec A
TLS trace: SSL_accept:SSLv3 write finished A
TLS trace: SSL_accept:SSLv3 flush data
connection_read(22): unable to get TLS client DN error=49 id=18
connection_get(22): got connid=18
connection_read(22): checking for input on id=18
ber_get_next
TLS trace: SSL3 alert write:fatal:protocol version
ber_get_next on fd 22 failed errno=0 (Error 0)
connection_read(22): input error=-2 id=18, closing.
connection_closing: readying conn=18 sd=22 for close
connection_close: conn=18 sd=22

The client does not present a certificate so the "read client
certificate" errors are to be expected I think.
